"f tropic countries where the tracks of the narrow and standard gauge roads are usually uneven and derailmentof the cars will be frequent unlessV thereof is sufficiently exible to allow the superstructure 'andunderframe'to so yield and conform to the irregularities of the track as t0 maintain fairly uniform the wheel loads thereon; and the object thereof is to provide a light metallic roof, for railway and possibly other cars, which is both extremely exible and substantially Waterproof and, whenever desired, can be so constructed as to afford ventilation for the interior of the car. l' Y 'Ifo this end, my new car roof consists, essentially, of a series of transverse channels, with flanges upturned, which also serving as carlinesextend across the car at spaced intervals, sloping downwardly from the ridge to the eaves on'each side thereof,` a series of transverseroof plates, intermediate fthe channels, thesides of which overlap the adjacent sides of two adjo'in` ing".` channels and vterminate in flanges down- Iturned within the channels, and a series of relatively narrow transverse cover plates which cover clearance for theofree lateral movement of the overlapping sides of the roof plates over the roofbut are in two series one on each of theopposite sides thereof and at their upperfends, adjacent the ridge, are provided with upturned flanges-the transverse cover plates, which may be brokeniat the ridge for convenience of manuside thereof and immediately `outside the `flanges at the upper ends oftheopposed roof' plates to provide shoulder abutments ,for their` flanges, and asingle longitudinal Acover plate with downturned flanges along its sides is mounted over the upset central ridgesections of the transverse cover plates and,overlapping the anges on the upperV ends of; the roof plates, covers the opening' between them. ,A feature of the roof is that itis, or can be,` constructed without bolt holes, inthe roof plates, to become enlarged with Ywear and leak, in the` bottom of the channels inside the eaves of the ,car, which holes also, may leak.

U Referring first toFigs. 1 to 3 of the drawings, the reference numeral'l indicates twoof `the usual side stakes'with which the superstructure. of a car is framed, 2 indicates the` longitudinal Z- shaped eaves-members which are mounted upon,v the sidestakes on the opposite sides of the can` and 3 indicates the side sheathings with which the car frame is closed and are here shown* as provided `with' Ventilating openings li lon each side and immediately belowthe eaves-members.

The transverse channels, which may be re#- garded both as frame and roof members, are

placed at 4spaced intervals and, `sloping downend each roof plate is bent upwardly to provide an upturned iiange 8 the edge of which is preferably curledvover. to form an' outwardly and downwardly projecting lip 9, and along each side is bentupwardly outside of and at a short distance from the `adjacent flange of a channel, and

then over and downwardly withinthe channeL,

thus forming a relatively wide lateral inverted trough lli which extends and is normally centered over Ythe flangeof the channel.V 'I'he transverse cover 5 plates, U extend from` side to. side of the shoulder abutments and covering the opening between the adjoining upper ends of the roof plates.

2. A car roof of the type described comprising transverse channels with anges upturned, roof plates arranged in series on the opposite sides of the ridge with upturned flanges at their upper ends adjacent the ridge and-sides overlapping each the side of one of two adjoining channels and shaped to provide an inverted trough extending over the ilange of the channel, transverse cover plates mounted over and covering the channels and the adjacent sides of the roof plates with suicient clearance to allow the free lateral movement of the roof plates over the anges of the channels and bent up on each side at the ridge to provide a shoulder abutment against which the anged upper end of a roof plate may bear and be held against outward and downward movement, and a longitudinal cover plate with downturned flanges along its sides 7 supported upon the raised central ridge sections ofthe transverse cover plates and covering the opening between the upper ends of the opposed roof plates.

3. A car roof of the type described comprising transverse channels with anges upturned, roof plates arranged in series on the opposite sides of the ridge with upturned anges at their upper ends adjacent the ridge and sides overlapping each the side of an adjacent channel and shaped to form a relatively wide inverted trough normally centered over the ange of the channel, transverse cover plates with downturned flanges along their sides mounted on posts xed to but not piercing the webs of the channels and with a clearance to allow the free lateral movement of the overlapping sides of the roof plates over the flanges of the channels and bent up at the ridge to pass over and provide shoulder abutments for the anged upper ends of the opposed roof plates, and a longitudinal cover plate with downturned anges along its sides supported upon the raised central ridge sections of the transverse cover plates.
